Bmw mini coolant leak

2005 Mini One has a coolant leak which only seems to only leak after being left overnight. There are no signs of coolant in garage but when the car is taken out onto the drive and is running it will drip for about a minute from either the rear of engine or under the bulk-head. It is definitely anti freeze as it is blue and the level is dropping. After it has lost a certain amount of fluid it seems to stop. Any ideas?

It could be a number of things. I had a coolant loss not so long ago (3weeks) and it was down to a hole in something near the gaskett where the coolant goes in and the coolant was being burnt off in the engine.

Take it to the stealer dealer and they will run a pressure test on it and find out where its coming from.

If your under warrenty still there shouldnt be any charge.

Have a good look at the header tank its self, this can sometimes have a split on the centre joint. This may explain that the leak stops when it reaches a certain level and leak appears when running as when the coolant gets hot the tank will expand and open split more.
Good luck as you need to get this sorted asap now the cold weather is on its way.

Just had the same thing in my 2005 Cooper.... It was a crack in the housing & had to be replaced. Ofcourse, I am at 53K miles, so my warranty was done. Cost me $300.

Ive had it happen to me 2 times on my 05 cooper, and i think a third time but I sold the car before I got a chance to check it out. It was the thermostat on both occasions. The car is out of warranty, but being a recurring problem they fix it for free.

I have the same problem, with my 2005 s with 59000 miles. I'll be taking it in for a pressure test. Mine only leaks after a long drive, then it sits for a couple of days and leaves a small 1 or 2 oz. puddle on the floor. But it does not do it all the time. About once a month!

Hi, had what I thought was the same problem on my 2002 Cooper. Changed the thermostat and housing today, went back after a few hours and the expansion tank was empty along with a passenger footwell full of coolant!! Any suggestions? Sorry to piggy-back the post...

Check your heater matrix radiator..........it can leak into passenger footwell!
Access it behind the black plastic side panel on the heater assy in the passenger footwell...........one of the side panel screws is difficult to get at.
